In response to my laments about not being able to use Intel 386 assembler in
GNU C, Ken wrote the following letter (he asked me to post it - here it is):

piece of cake!

What you do is get MASM6.11, which has the option
to create coff-style object files, which is what djgpp expects.  These object
files can then be linked in with other djgpp-produced .o files to form
your program.

Of course, your assembly code must already be 32-bit protected mode, and you
must use the djgpp procedure calling conventions
(which I believe are "push bp" on procedure entry and "leave", "ret"
on procedure exit.  Compile a function with djgpp and look at the object
file to see the calling convention it requires).

I did this to create an assembly routine assembled with MASM called from
C compiled and linked under djgpp.

p.s. if you need explicit detail, I have the files/makefile at home.
However, the exercise of figuring it out is useful in itself.
